You are most likely not going to get more than 3 years out of most pool bubble blankets. Even those with a five year warr. If you are dragging the pool cover over the coping (abraision) and leaving it on the hot pool deck (cooking or burning) or grass in direct sunlight then you have virtually cut the life of the cover in half.

Consider a very good quality cover reel system. The best one is made in Canada -- Rocky's Reel. I have tried all the rest and find they are useless. Ken
Epithelium is found covering external or internal surfaces in the body. Stratified epithelium consists of more than one layer of cells. It is often found in situations subject to abrasion, where the top layers of cells are worn off. Layers underneath replace the lost cells, so the basic function of stratified epithelium is protection. See: http://ect.downstate.edu/courseware/histomanual/epithelia.html
